Consistent Strain/Stress Lag Eddy-Viscosity Model for Hybrid RANS/LES

摘要: The paper presents a comparison of two hybridization techniques between RANS and LES, their potential limitations in an industrial context. first part the also attempts to address often eluded problem hybrid RANS/LES scommunity: importance baseline statistical model. A new robust low-Reynolds number eddy-viscosity model, derived from Reynolds-stress model accounting for lag stress strain is extended Detached Eddy Simulation (DES), compared with most widely used DES dual-mesh approach, where scale-resolving simulations are performed on separate grids, drifts terms allowing recover accurate solution each grid, assessed simple case.
